ATENT CHARLES F. VERRELL, OF GRAND RAPIDS, MICHIGAN.

DUST-COLLECTOR.

SPECIFICATION forming part of Letters Patent No. 623,639, dated April 25, 1899.

Application filed May 5, 1898. Serial No. 679,819. (No model.) I

To (1,7 7 whom, it may concern:

Be it known that I, CHARLES'F. VERRELL, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Impro velnents in D ust-Oollectors,of which the following is a specification.

-My invention relates to improvements in collectors in use for separating dust from the air that conducts it, by the use of blowers, from planers, saws, stickers, &c., to shavingsbins; and its objects are, first, to stop its course around the inner surface of the separating-chamber, and, second, to facilitate its discharge through the-discharge-tube. I accomplish these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a cross-section of my collector 011 the line y y of Fig. 2, and Fig. 2 is a vertical section of the same on the line 00a: of Fig. 1.

Similar letters refer to similar parts through out both views.

In constructing my dust-collector I use the ordinary separating-chamber A, the air-chamber G, having cushioning-chambers a and g and a discharge-port H, an inlet-port B, and a dis;:harge-tube for the dust, (represented at F.

My invention consists of the peculiar construction of dust-guides O, C, D, and E.

It is of course understood that the dustladen air enters the separating chamber through the inlet-port B, and after passing around the inner surface of the chamber, as indicated by the arrows, the purified air passes out of the opening H, while the heavier dustladen air and dust escape through the clustdischarge tube F.

The portion C of my conveyor-wall stands at a slight angle from the perpendicular and is constructed with a side wall 0 and a back wall 0, which is secured to the inner surface of the separating-chamber, so that it forms a trough which catches and stops the dust as it is passing and causes it to drop toward the bottom of-the chamber, when the currentof air below its lower end will carry it along the surface of the greater incline C, which conducts it to the vertical wall D. The portion 0 of the guide forms a narrow wall that stands at right angles with the surface of the wall of the chamber, and the wall D stands at right angles with the bottom of the chamber, striking the line of the periphery of the dischargetube F at a tangent, and from the point of contact it forms a wall nearly around the opening, forming a continuation of. the tube above the bottom of the chamber, which diminishes in height until it comes to a point at the bottom of the chamber before it has entirely surrounded it.

To complete my invention and make it fully effective, I find it very desirable to place a cap E upon the end of the wall D that surrounds the opening of the port F in such a way that it will overlap the opening a portion of its diameter and form an inclined guidingwall that will conduct the dust downward toward and through the port and will prevent any of the outflowing dust from escaping over the top of the vertical guiding-wall.

The portion 0 of the guides is not an absolutely necessary element in my invention, as the dust will find its way to the portion 0 and to the discharge-port without it; but 'I find that it greatly facilitates the action of the separation.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a dust-collector,a separating-chamber having proper inlet and outlet ports, in combination with a slightly-inclined vertical guide, extending from the top to near the bottom of the chamber, said guide having side Walls to form a trough at the inner surface of the wall of the chamber, a sharplyinclined guide leading from the lower end of said guide to the top of a vertical guide near the inner edge of the inlet-port, a vertical guide extending from the bottom of the chamber to a line connecting with the lower end of said second guide and extending thence to intercept the periphery of the dust-discharge at a tangent and to pass a portion of the way around the discharge and tapering down at an angle to meet the bottom of the chamber, and a cap upon said tapering portion which projects over to cover a portion of the discharge-opening and act as a guide to conduct the dust down to and through the discharge, substantially as and for the purpose set forth.

opening of the discharge'to form a guide to conduct the dust to and through the discharge, substantially as and for the purpose set forth.

Signed at Grand Rapids, Michigan, April 30, 1898.
